Tolong banget ya kak
Jawaban:
1. x² = 6² + 8²
= 36 + 64
= 100
x = √100 = 10 cm
y² = 10² + 24²
= 100 + 576
= 676
y = √676 = 26 cm
2. (x-1)² + 15² = (x+8)²
x²-2x+1 + 225 = x²+16x+64
226 - 64 = 16x + 2x
162 = 18x
x = 9 cm
3. perbandingan segitiga 45°
x = √18 / √2 = 3 cm
Jawab:
pytha goras
segitiga siku
1. x² = 6²+8²= 100
x = 10
y² = x² + 24²
y² =100 + 576 = 676
y = 26
2. (x - 1)² + 15² = (x+ 8)²
x² -2x + 1 + 225 = x² + 16x + 64
-2x + 226 = 16x + 64
-2x - 16x = 64 - 226
-18x = - 162
x= 9
3. segitiga siku sama kaki
x² + x² = (√18)²
2x² =18
x² =9
x = 3
